Title: Apparatus and method for pressure management
Inventor: DABIR REZA R
IPC: A47C27/00
Filed: 2002-05-24
Abstract: An apparatus and method for alleviating excessive pressure development on a body area includes a cushion having bottom and top surfaces which are spaced apart. The top surface has a plurality of channels formed therethrough.   A compressible inner layer is disposed between the top and bottom surfaces, and a plurality of elongate, inflexible members are supported by the inner layer and are disposed at least partially within the channels. The members have first ends that extend through the channels to project beyond the top surface. Pressure applied to the first ends causes the members to be displaced axially along the channels toward the bottom surface without deformation. Pressure produced by body contact creates point pressures on the body area, and displacement of the members maintains the plurality of point pressures on the body area, alleviating excessive pressure.  The apparatus includes a enclosure cover and the members have large, tapered ends.

Title: Methods for profiling and classifying tissue using a database that includes indices representative of a tissue population
Inventor: JOHNSON PETER C
IPC: G01N33/68
Filed: 2000-06-23
Abstract: A sample of normal tissue specimens obtained from a subset of a population o f subjects with shared characteristics is profiled in order to generate a plurality of structural indices that correspond to statistically significant  representations of characteristics of tissue associated with the population.  The structural indices include cell density, matrix density, blood vessel density and layer thickness. Alternatively, the sample of normal tissue specimens obtained from the subset of the population of subjects with shared  characteristics can also be profiled in order to generate a plurality of cel l function and/or mechanical indices that correspond to statistically significant representations of characteristics of tissue associated with the  population. Structural, mechanical and/or cell function indices for a plurality of tissue populations are determined, and then stored in a databas e. The database information is then used to classify tissue specimens (e.g., human tissue specimens, animal tissue specimens, plant tissue specimens, foo d tissue specimens, or manufactured tissue specimens) provided by a user. In particular, a user measures parameters (e.g., structural, mechanical and/or cell function indices) associated with the user's tissue specimens and then compares this information to corresponding parameters for normal tissue in t he database in order to classify the user's tissue specimens as either normal o r abnormal.

Filed: 2003-04-09
Abstract: Cascade low-pass filters are useful in attenuating the xDSL band in a POTS splitter. The design of the low-pass filter is a sixth-order filter having two stages. A first stage includes a fourth-order filter, preferably with a stop-band frequency of approximately 48 kHz. A second stage includes a second-order filter in cascade with the fourth-order filter. For this filter, the stop-band frequency is preferably approximately 29 kHz. The inductance value of the second stage is relatively small in comparison to the inductance values of the first stage. In this manner, improvements in xDSL band attenuation are facilitated with little or no eroding of the voice band performance such as insertion loss, pass-band attenuation and return loss.
